qwidget_p.h: Remove DontSetCompositionMode from the internal flags

This flag was used by QWS to set or not set the composition mode
when filling the background. E.g. this was used by 'transparent'
windows to set the alpha bits. QPA didn't have this enabled in 4.8,
the code paths are gone in Qt5 and it is the responsibility of the
QPlatformBackingStore to initialize the alpha bits properly.
